A member of the military serving as one of Donald Trump's valets has tested positive for coronavirus.

A White House spokesman said the president, and Vice President Mike Pence, have since been tested negative for COVID-19 and "remain in good health".

It is the latest coronavirus scare for the president, and the first known instance where a person who has come in close proximity to him has tested positive since several people present at his private Florida club were diagnosed in early March.
